107 kit with se110 heads

They will bolt on alright but your motor's going to be a dog. Wrong valve sizes, wrong static compression, wrong porting, wrong spring set-up, wrong combustion chamber profile, etc, etc, etc. They may in fact be totally useless. How many more posts do you feel you need to get the fact that those heads are pretty much unusable without a lot of expensive work, where as your stockers off of your bike would be easier and less expensive to get worked over for what you need for your motor build.

Its the combustion chamber size that will give you trouble. Flat tops with the 95cc chambers in the 110 heads will drop your comp ratio a lot. Stock is around 85cc. I'm sure FM has 107" pistons they can supply to work with those heads.

when I was building my 06 88" last year I wondered the same thing. My builder said he wouldn't even work on the SE 110 heads, and he could make stock heads perform much better. Guess he knew what he was talking about...motor dyno'd 120 squared.

Thank you guys. I talked to the guy I got them from and he said he'd have no problem taking them back and refunding my money looks like I probably won't do heads when I do my 107.

ebay them
If you paid 100 bucks for these you can easily get 4-5 on ebay... guys use them on the big motors all the time...just not worth it on a 107 build.
