Would the real Motorcycle Mechanic please stand up ? ?

A simple table like:
If you are at sea level & have a carb'd 865:
Fit a Pieman igniter, remove the Snorkel, drill the slide to 3mm, fit 42 pilots, mixture screw 2 turns out, fit D&D pipes, fit DNA filter,
change main jet to 125, now your bike will produce 75HP @ the rear wheel !

That would be a 135 main jet and around 62-63bhp @ the rear wheel & 65-66bhp for an EFI :ride:

A good manual, some common sense, trial and error, and advice from someone that has been there and done that before. That is about all you need and a forum like this is priceless when it comes to that. I pretty much do everything on my bike now and this forum and youtube is used almost as much as my toolbox.

yeah your right Ben, :)

I just wish 'cose most of these guys have done it all before & either been very successful or have stuffed up, it would be IMHO a damn site easier for a newbie to the forum & someone new to Triumph, to just to select their bike and the mods desired, suiting their budget & away they go, a simple written chart that if followed reasonably closely an outcome would be assured. like I suggested earlier:
"If you are at sea level & have a carb'd 865:

very simple, no pain !

Not everyone just want to tinker about trying to set new landspeed titles etc & race their machine, if they did they perhaps would buy a different Brand,
but most do want a machine that's reliable, fun & great to ride, that's a well tuned Triumph Twin !

I know it's been said that even though our Bikes are the same Machines pretty much, there may be some small differences, but it certainly would be a great starting point for some & more than good enough for many others ?
saving all a truck load of $$$, time & headaches too.

Incidently, for those who are interested or concerned from my beginning post, my machine is going like the showers, simply rocketing along and so much fun to ride, so much so, I stayed out riding all day ! :)

just had a great ride again today mate :woot:

Couldn't agree more mate it would make life a lot easier and having recently gone down this path it would have been awsome but all of you helped me out so much I would have been lost. However I think a sticky thread just as you described for each machine would help us all out a great deal cheers and go for a ride mate weather today awsome,bad side is I am working:up:

1977 AMI grad, worked in the field at a Brit bike place for 1 year and moved on w/me education. Now a retired chiro.

Yet I lok at a new Bonnie and think I can tear it down and build it back in my sleep but probably would have to end up selling the parts on Eboy.

I'm more in agreement with BlueJ as far as modding your bike to personal tastes. A guy with a stock engine might want to put his buckage into suspension bits and tires for better handling in the twisties. A guy might want better power and taller gearing for the long interstates in the US. We all like to set our bikes up for our tastes.

HD offers stage one performance mods. Then stage two and so on.

One of the great things about a new bonneville or thruxton is the "basic" engine and the way the bike is set up. Folks that like to work on their machines, who don't want to choose modifications from an option list at the dealers, can fairly easily work on these bikes. Yesterday I looked at a friends Duc and a Sus and it looked like a hornets nest to me. I looked at some forums for other machines in our sale price bracket and they all looked liked the mods and aftermarkets were a lot more expensive than us.

Bottom line for me.....reasonably priced new, great buys used, great handling bike out the door, tough proven, easy to work on, most junior wrenchers can take a stock bike and get into the 90hp range and tune the suspension themselves and have a great performing machine and have the satisfaction, for me the great thing, of having done it yourself. I also like learning new shit and it seems that there are a LOT of bonne/thrux owners that mod things and pass on the knowledge......fun shit.....best

And if you're going to spend all that money the Predators, you should pull the airbox altogether and go to about 142-145 mains!

Question: With EFI, are there still jets?

I thought it was a very fair question. I am just suprised that there are really no trained Triumph mechanics on the site.
I think that REALLY says alot both about the ability of our bikes and even more about the soul and passion of the many riders. I myself am not a trained mechanic but i enjoy working on my bikes and cars. I often handle most problems that come up on my auto's, be it water pump,tune up's,sensors,oil changes or horse power mods.
I mean let's face it how many of us have taken our bikes or auto's to "trained mechanics" only to get them back and they run the same or worse.
At least when we do it we know it is done right, or we prey it is done right , and we take pride in both a job well done and the appearance and performance of our bikes and in some cases auto's.
So, let's raise a glass to all those with the passion and courage to do it yourself. To those who dare and learn so that we may pass it on and keep these bikes on the road.
Cheers.

Actually there is at least one certified /trained and currently making a living at a dealership in south FL.
I do not remember his screen name, sorry.

He chimes in here occasionally and over on the NTBF .

Depends on which pods you use. With DNA pods and 42 pilots, 155 mains are right, with 40 pilots, 160 mains do the job.

No jets with EFI, just numbers.

There are very few Triumph certified mechanics that know much about tuning our bikes, to the extent that they would have no idea what jetting to use on a carb'd bike for just removing the air box baffle. Unless they are twins enthusiasts, they just don't get the training or exposure.

Yeah as far as Triumph mechanics being the be all, end all - The only two Triumph dealers around my area aren't really what I'd call Triumph experts. They just sell the bikes.

One dealer was just an Arctic Cat, Victory, and Kawasaki Dealer and the other sells everything from Ducati, to Kawasaki, to Royal Enfield, but they're preeminence is Ducati.

Basically, what I'm saying is just because the building says Triumph doesn't mean there's anyone inside it who knows more than an above average mechanical person who has a passionate interest in the bike.

I'd give my bike to someone who loves the bike and has been tuning them for 5 years over someone who loves making a buck and has been selling them for 10.

There is no training out there for getting hp out of these bikes .Why because we are learning as we go.Alot has changed in the last few years.Alot of testing is still going on.
If you want to hot rod these bikes learn the right way to tune them yourself then no mater what you put on your bike you will be able to tune it.If you are working with a carb bike learn what does what in the carbs you are useing then you will know what you need to change.Spend the money buy a a/f gauge worth with that find what seams right then go to the dyno and find out.Any other way you are just guessing and 50% of the time it wont be right.

I took my bike to the local dealerships in order to fix a problem that occured soon after they did a service. They kept the bike for two months (granted it was Winter so I was not in a rush). They had an answer for everything but no solution to fix it. After getting advice from this forum I demanded my bike back and fixed it easily. Had I listened to the dealership mechanics I would have been out a lot of cash.

From then on I have not taken a bike to the dealer mechanics as i feel they are not working in my best interest.

The dealer where I bought my Bonnie black had all "Trained Technicians" but they were all 18-19 year olds. I took my Bonnie in for what I had diagnosed as a bad coil, I told the Tech to check the coil, after three hours I saw the Tech at lunch with the other Techs and as I walked over he said to the others "that is the guy that F@#cked up his carbs when he rejetted", I looked in the shop and he had my carbs completely off and ready to be taken apart. So a quick visit to the manager and my carbs were put back on and he swapped out the coil and it started right up.

I started riding Triumphs right after Meriden closed and there was no dealer network anymore and while I am no expert I learned to repair what I had.

Unfortunately "Techs" are mostly what you get anymore not true "Expert Mechanics".

I am not saying where are the real trained Mechanics per say, nor am I suggesting that we select from a list at some dealer all the mods we want either, this forum does have many knowledgable characters who do know & in most cases know much more than the dealerships who are only selling the product. however there are as in most cities people who specialise in tuning motorcycles, often with a race background. We in Melbourne Australia are lucky to have one such Guru of Triumph Tuning, Asian Charlie.
:) Although much of what Charlie does, is secret to protect his lifestyle & business. :c

But what I am trying to say, I still think that to make it more simple specially for a new to Bonneville owner, a new list of tricks could be formulated just as Pieman added to my sample list, where someone or many who have the expertise & has proven this by having their bikes perform day after day after day, help compile a list of simple stages that anyone can follow and receive positive gains without all the mistakes & wrong purchases in the beginning as some are lead to do. :banana:

But just as shown here between Pieman & BlueJ
Pieman - " with DNA pods and 42 pilots, 155 mains are right, with 40 pilots, 160 mains do the job."

BlueJ - " if you're going to spend all that money the Predators, you should pull the airbox altogether and go to about 142-145 mains!


The treatment is still hazy ? :d
