I'll have to update this thread it looks like. I did a handful of things to really help the CR150F out.
- New Dunlop tires were a must and really changed everything
- I removed the stock baffle out of the exhaust
- Larger main jet and slightly larger slow jet
- One tooth larger on the front sprocket helped a ton
- Clean and lubricate all linkage bearings
- Acerbis handguards should be mod number one
- Renthal high bars (super strong)
- Pro-Taper waffle pattern grips
- Sparkplug upgrade
- New Uni air filter
- Front fork spring spacers (mandatory)
All of the things I did above were relatively inexpensive and made a huge difference. The little CRF is just the easiest bike to ride but with the above mods the bike sure can move and shake right down the trail and hold a pace that really surprises people. I just wish I had something like this to learn to ride on instead of the firecracker of a bike I started on: a 1986 YZ80! Even straight from the showroom floor this the bike needed to richened up quite a bit. The parts to allow more fuel to flow through the carb are near nothing and if you can assemble a radio controlled toy car you can surely install new jets in a CRF150 carb. I'll have more on this later here on the forum.
