Would you happen to have links for either of these? Thanks

I have a stock head, pilot jet is a 25, needle in the 3rd position, mains are 300's, FMF Fatty with Core2 silencers, K&N filter and Power Lid and Boysen Carbon Fiber dual stage reeds on stock cages. I'm also adding the Rick Stator timing plate this weekend and advancing it to +4. It bogs pretty badly in the low end, should I change to a 27.5 pilot jet? Or just adjust the air screw? Thanks a bunch, your help is much appreciated...

Well, from everything I've read here, it sounds like advancing the timing gives the biggest bang for the buck, and also porting. The coolhead seems like it's a convenienve thing and a lot of money for little return. I'll be going with the Rick Stator timing cover and start there. Then porting is next. Does this sound like I'm on the right track? I'm still running 25 Pilot Jets, do I need to change those out when advancing the timing? Thanks

So can I run this setup and find a significant amount of power increase, keep the stock carbs, and not have to have machine work done? Desired Setup The CoolHead with 21cc Domes Pilot Jet: 30 Needle: 4th or 5th position Main Jets: 300-320 Exhaust: FMF Fatty Silencers: Core2 K & N: Filter K & N: PowerLid I am looking at this particular one: Coolhead Will the kit have everything I need for the installation and will the difference in power be extremely impressive? Also can I use this setup in conjunction with the Ricky Stator Timing plate advancing it to +4. And what kind of performance increase do you get from the timing advancement? Also, I guess I'd need to move the needle from the stock position. Again, I want to get as much low end and mid range power as possible without having to do any machine work or killing the top end. Is this the right way to go about it? Also, will the performance increase be substantial from the Ricky Stator Timing plate set at +4? Thanks

One last mod I forgot to mention, is the Boysen carbon fiber dual stage reeds in the stock reed cages, but they should be miner compared to the "Desired List" changes I mentioned above. Will everything I asked about work well with each other? Thanks a bunch!!!

I mainly ride trails and MX tracks... I'm mostly wanting the most low and mid range power, and the responsiveness that'll snap your neck, but I don't want to lose the top end either. I do realize there is a trade off, but I'd like to think there is a happy middle ground. Again, my elevation is 430' above sea level, and temps are in the 90's the majority of the time, Dallas, TX. Current Setup Stock Head Pilot Jet: 25 Needle: 3rd position Main Jets: 300 Exhaust: FMF Fatty Silencers: Core2 K & N: Filter K & N: PowerLid I spoke with a guy at Duncan racing for almost an hour today, and the setup he came up with is as follows: Desired Setup The CoolHead with 21cc Domes Pilot Jet: 30 Needle: 4th or 5th position Main Jets: 300-320 Exhaust: FMF Fatty Silencers: Core2 K & N: Filter K & N: PowerLid I am looking at this particular one: Coolhead Will the kit have everything I need for the installation and will the difference in power be extremely impressive?

Also, I guess I'd need to move the needle from the stock position. Again, I want to get as much low end and mid range power as possible without having to do any machine work or killing the top end. Is this the right way to go about it? I'm basically summing up this thread and want ya'lls final feedback. I really appreciate everyone's info on this! :smile:

Do carbs and portwork have to be done at the same time? I guess if the carbs are bigger, the head needs to be able to accomodate that? Does that sound correct? Or am I way off? Thanks again

My elevation is 430' and I run 93 Octane and would like to continue running 93 Octane. What all is involvled in advancing the timing? Thanks for all the help.

So just mount the cool head on and go? Will just the cool head give me a noticable power increase, or does it need to be done with the timing advance?

I've been looking at the cool head, does it add much? Do I have to do much to the rest of the motor to add just the cool head? Also, the advanced timing, what all is involved with that? Sorry the question is so generic, but I haven't done much with advancing the timing. Thanks, Sneed

I am running out of bolt of performance things. so I think. I have FMF Fatty's, K&N filter, PowerLid, jets, Boysen reeds... What else can I do that has a good bang for the buck performance wise and is fairly bolt-on. I have no problem gettying into the motor, just don't wanna get into the thousands of dollars for mods. What have you guys done that had the most noticeable power increase? Thanks, Sneed
