Ok, this is how it is. I have a 1987 R. But i dont have a motor 4 it. I used to jump my blaster and everytime i jumped it the front end usually came up so high. idk if thats me or if its with 2-strokes that its hard to controll in the air or whether its just b/c its so light. But then i was jumping my warrior over some doubles and it was perfect landing everytime. So as of me experencing 4-stroke to 2-stroke jumping i like the 4-stroke better. So im deciding on getting a yz426 motor for my R or just a 310/330 motor... IDK WHAT TO DO! any suggestions please

I would say that the front end coming up was more to do with the blaster chassis and swingarm than the 2 stroke engine. Its all about the weight bias front to rear. The R will jump much better than the blaster did no matter what engine is in it. I would stick the the R engine. It is cheap to build and maintain and will fit right in without problems. Home built hybrids are hard to get right. They often turn into a mess.
ah.. i dont know what to do. b/c if this jumping problem continues with the R then idk. I feel more of the power wwhen you need it on a 4-stroke. i mean putting the engin and make it fit real good is no problem i have a buddy of mine that could do it for free so yea im not really sure

dude trust us its not a 2 stroke thing its the blaster ^_^
the 250r jumps way better. when i rode my cuzins blasty it was completely diffrent its due to the shorter wheelbase so more of the wieght it toward the back. adn the 250 sails thru the air like an air plane. juat stick with the 250 engine and you should be golden. ive had my motor since the showroom floor when my pappy bought it and it still runs strong. that 20 years on the factory parts. let see a 426 do that! ^_^

Trust me, the blaster is so small and short that the chassis is your problem, not the engine. If you build your R engine right, and you know how to keep it in the powerband, you will have no trouble. A good mx port and mx pipe will give you great snappy power to get over jumps just fine. I mainly only jump in the dunes, but I typically just hold a steady throttle up the face and it flys nice with a slight nose up which is what you want.
i'll be another that will say that its a blaster thing. lmao for the life of me cant jump a blaster without having it jyro the front up(i'm sure it's the short wheelbase). i have a >lil< nephew that can jump it all day long and even manuver a right and left jyro in the air but cannot jump an R. ofcourse he grew up on this machine.
