hey guys, Im new to this forum, I just got a cheap 97 xr100 and I want to throw a big bore kit and exhaust on it. I was just trying to pick between the TrailBikes 115 kit and the BBR 120 kit...if you have any info/reviews of either Id appreciate it

Thanks

ive heard a few people have had problems both of the bbr kits, as in the xr120, and the ttr150 kit. my uncle had a cracked bbr ttr150 sleeve, and ive heard of it happening on the 120 kit as well

none of them are on pm, so youll have to trust me

takegawa makes an awesome head if you have crazy money to spend

trail bikes stuff is very good quality, and most always cheaper too

The cam that comes with the TB kit is pretty tame, but it's tough to beat the price of the kit. I think I've seen the kit without the cam for $150. Add a Web 69/68 and some springs, and clean up the port short side.

I saw several broken BBR sleeves so I sleeved the stock jug and used a Wiseco forged piston. The cases need to be opened up a bit with a dremel but the added durability is worth it. I lightened the crank a bunch while it was apart, since the stocker weighs a lot more than the 80. Lightening the flywheel helps it rev quicker too. Open up the airbox, add a 115 main jet and she'll move pretty well. I used an 80 trans for the closer ratio gears.
