Yes I know I haven’t been here in a long time and I’m like a child running to the parent after getting hurt but not needing them beforehand.

So I still have my Job and my 2007 Bonneville which now has 11,000+/- miles on her. I ride it 20 miles R/T daily to work and home during Spring, Summer and Fall but have not really been able to enjoy weekend rides anymore as a result of being a homeowner. It has been problem free up until 2 weeks ago.

I stopped riding it in late October when the leaves were everywhere in New England. I had it sitting in my garage for over 6 weeks and was starting to get nervous about the gas going bad so I wheeled it out and started it up and let it run. I went to move some leaves with my backpack and took a look back at her around 15 min later and saw smoke. I shut it down and saw it was leaking somewhere on the lower part of the engine. Sorry to say that these days I don’t keep it very clean so finding the leak was not possible. As I have been experiencing full throttle clutch slippage over the summer I decided to replace the clutch springs. Since I really don’t have the time anymore I decided to just drop it off at the dealer and let them take care of that while finding and repairing the leak and doing a 10,000 mile service on it including the valve adjustment.

I decided to do it on a Saturday and when I went to load it up on the trailer I noticed that there was a pool of oil below the engine on the garage floor; about ½ - ¾ of a cup. I thought well this is no good. I dropped it off and about 5 days later I get a call that when he went to check the clutch he smelled very badly burnt oil. I use Mobil 1 10/30 synthetic with a Purolator oil filter. They said that both oil pumps were melted and the gears were completely broken. $1250 total to repair and complete service. I entered a state of depression.

An hour later I see the dealer trying to call me again and I immediately think this is probably more bad news. I answer and they tell me that they proceeded to begin adjusting the valves but with the spark plugs out they could not hand turn the engine. They now think the crank and bearings are broken as well. They want me to come in so they can show me the explanation. I now felt completely nauseous. At this point I can now see that everything is probably scored so I’m now thinking that the engine is either a basket case or needs a total rebuild. But if I do a total rebuild how do I know the integrity of the case and any of the remaining parts inside. I’m now thinking that I should probably do an engine swap.

Anyone know where to get a 2007 engine? :mad2:

this may be oil related as 10/30 is too "light" for an air cooled engine
should be 10-50
I use Purolator filters too without problems but I use Mobil 1 15-50 or LubroMoly 10-50 in all my Triumphs
I have an 07 675 engine for sale and I'll ask around for a twin
eBay may be your best bet; they have a few 270 motors that may require only a new igniter

My heart hurts for you mate. Google salvage yards, they usually sell motors out of wrecked bikes that have almost no miles on em. i think for around 12-1500 you can get a new motor to swap in instead of thee 3-4k to rebuild completely

Hedge…..go to Pinwalls/Ebay….they have a 2012 T100 engine for $1600. I have had great service and luck with Pinwalls. Peel off your carbs and bits from your engine and you have a runner again.

I think you will need some electronics to make an EFI engine run with carbs

Yeah, I think a flywheel out of a carb'd motor and you should be golden. At least that's what I've been told. If so, could you salvage the flywheel out of your 2007 motor?

PS I'm in eastern CT, near the casino, and have the facilities to swap out an engine

I might just take you up on that Doc - if I trailered it up on a Sat real early do you think it would be a 1 day swap?

My Flywheel is fine so if that is all I need then this might be a good deal. However, there is very little info on this motor on eBay and the guys in FL don't know a lot about it except that they claim they fired it up and it runs good . . . of course :wack:

That would be awesome Doc. My plan is to go pick it up tomorrow and roll it into my basement and cover it. Then when I get some extra cash and can find an engine I will buy it and contact you. In the meantime I'm looking at a Honda CB1100 like Bud's but in Black.
 
Another item to keep in mind, you may want to look for a pre-2012 (non can-bus equipped) engine. My understanding is with the later model EFI bikes, you can't replace the OEM speedo for mechanical without finding a work-around that will allow the bike to start. This may be the additional electro work drlapo was referring to.

From what I hear, the moto-gadget m-TRI module is the only kit on the market for this work-around. And at 338.00 Euro, this is a pretty expensive work-around.

Not wanting to link, if you're wanting more info, you can go to the motogadget website and use their search function to find it.

I only came across this as I was exploring the idea of installing smaller gauges on my 2014 Scrambler.

That's sad times.
I saw that happen to an almost new Kawasaki once. Hadn't been run for a while and he started it up and let it idle to long and with no moving air and low oil pressure from low rpms for to long it fried that engine.

When I start a cold engine I don't let it idle for more than a bit before I give it some RPMs to get the oil circulated through out the engine. Also no moving air past a running air cooled engine means it will get hot in a hurry.
Hope you find a good deal on an engine.

Thanks all - got the bike home yesterday with the help of Uncle Charlie. We inspected the cams and they are perfect. Riddle me this - if your oil pumps fail and the engine gets starved for oil, isn't the first place to starve, burn and seize, the top part of the motor? Well the top is perfect. Where I'm having trouble understanding is that with the plugs out it is very hard, not impossible, to hand crank the engine over with a big socket wrench. However it cranks with the starter motor. I think I have to pull the engine and inspect the crank, bearings, rods, pistons, rings and cylinder walls. Wish I had a bore scope

I seem to recall somewhere that these engines have two oil pumps which would explain this.

Yo are correct but both failed and both plastic gear drives melted. I have to believe that even though both failed somehow either the small pump or larger pump still scavenged some oil up or the top end would have been the first to go - no?
