Does anyone know of anywhere I can get a big bore kit for my ttr 110 for relatively cheap? Also I want a clutch kit but can do without if need be.

You have to bore the stock cylinder for these.
Otherwise you can bore the stock cylinder to fit a 1st over wiseco klx high compression piston such as this member did:

For the price of a bore job and a piston gasket set you can get oem 125 topend with head (hint 124 head has bigger valves).

TTR110 can be moded easily, here's I have a 58mm size piston with 69mm ultra thick sleeves for durability.

Even with 250cc engine and PWK38AS Solenoid it is easy

You know, to increase low to mid power and rpm range it doesn't always need a big bore. Just using a smaller magnetos & good ignition. You can using YZ125 magnetos, but you'll have to dam the oil from the crankcase.

This is the cover for the left crankcase.
