Ghost thread, spooky.
I done one of those mild 110 builds years ago. Cam, bore, slightly higher compression, Cobra exhaust and it felt a little better but not anything crazy. I'm a heavy rider too, so that little 110 was stressed in more way than power.
I rode it around a bit and decided to sell it. A little dude came by and rode it and it was like a rocket with him riding. If it only ran like that with me riding. I also put front suspension on it, which was the best upgrade.He bought it and I'm sure had a blast.
Anymore, I'd just buy one of the large horizontal clone engines which are more powerful and reliable than a 110 could ever be built into, for less money.
