I am wondering if it is possible to swap any bigger motor into a 93 600 F2. Like newer 600, a 750, or possibly a 1000? If anyone has any experience or could point me in the right direction, please do. Also, is if it would be easier, is there any place online where I can buy bigger cams and such to get more power? And also. I currently don't have a can or muffler on the bike. It just comes from the header out to about the right front peg and dumps(it was that way when I bought it). Is it harmful to the engine to run it that way, could it be the reason why it is running like crap right now? I'm sorry for all of the questions but I really want to get this thing running soon and I need some help. Thanks for any info you guys can give me. I really appreciate it!

 

Also, would plug brand make a big difference. Right now it has autolites in it(I've never liked them but that's just what was in it when I got it.), but I think it's supposed to have NGKs. I'm not sure.
Thanks again

 

It is said that it is "easy" to use a 900rr motor... Try searching the forum for a 900rr swap...

 

Thanks man! Much appreciated!

 

Not having a muffler probably isnt helping the engine for the sounding like crap. When i bought my F2 it had a two brothers racing exhaust on it that the previous owner decided to take all of the baffling out of, so it was essentially a straight pipe. I found a cheap stock muffler and put that on, and what a difference it made. Not only could I actually hear my friend next to me talking when the bike was running and revving high, but I could tell I had much better throttle response as well. Backpressure is always helpful to an engine, and having no muffler negates any backpressure pretty much.

 

Reading some of the other forums it looks like a ton of work to swap a 900 into a f2 600. I was wondering if anybody knew if it was easier to do a swap with a 600rr or f4i 600?

 

Search button lol I personally looked up all these questions. Not only that hover. Asked some, of them too u can do these swaps but need everything thay would go with the motor plus the fuel tank our a fuel pump from auto zone

 

Autolites are fine. i think its 4302 IIRC thats the cross for the ngk cr9eh9.. ive run both and am currently running the autolites for budgetary reasons.. i'm a cheapo. NGKS seem to last abit longer but are nearly triple the price!!

+1. I WILL do this swap when I get another stunt bike.. ultimate sleeper

 

and no, running can-less will not harm your motor, but you will go deaf at a young age... here is a link

Lol! Dude I have been around track cars running open headers, street/track cars running straight cut outs, and have worked aircraft engines for years. I am not really worried about my hearing. It isn't that load with a helmet and my MP3 player going. I have to ride a 100 Mile round trip every day. The sound doesn't bother me, and I'm not worried about it hurting the engine. I just want it to run correctly and smoothly! And that was what I was wondering about. Will just having and not having a actual exhaust can change the running, power, efficiency, and smoothness of the engine?
