Not when it comes to legal ownership and the right to sell them. Sentimental ownership isn't a legal construct.

I rode a 2006 CRF450R back-to-back with my 2007 CRF450R ---> 2006 was waaay gnarlier in terms of power delivery / snappiness --- it felt a lot faster (like 10%+). It was too much for me in that moment because I was so used to the 2007 CRF450R ... which reminds me how much tailoring 450F power has received over the years from manufacturers (KTM especially, as my 2022 KTM 450 SX-F is absolutely docile compared to the 2006 CRF450R motor, yet makes more power). My 3 cents is: Be honest with yourself regarding what level of power & snappiness...

7/14/2026 11:27am This is great info, thanks for chiming in. I bought this bike already completely modified for cheap, I am normally the guy that runs a stock bike and wont put anything aftermarket on it. I actually have another 06 crf450r that is completely stock. I think I will stick with the 06 head for now, i like the power that...

7/12/2026 11:46am The 06 has 1mm larger exhaust valves and yes the 06 uses the different compression release system. I'm only looking to change the head, I know all of the 06 parts interchange with all of the 07 head. I was just seeing if anyone preferred the performance of one head over the other. I'm leaning towards just going with another...

If I remember correctly, the ‘06 has larger valves. I think the 06 was the fastest crf450 of those years. I’d search and go back and read the mxa tests of the 06 &07. Should tell you what you want to know.

7/11/2026 10:16am I have a 2006 CRF450R with a Hot Cams Stage 1 cam and Pro Circuit Ti4 exhaust that will be due for a top end rebuild soon and I am trying to decide what head to go with. I have always ran the 06 heads but I know some people like the 07/08 head. Does anyone have any experience using...

Travis Pastrana Nitro Circus it's 2003 Daytona supercross and your factory Suzuki RM250 is waiting for you to win your heat race🤘🏼 Since i was little Travis has been one of my biggest idols and finally getting to meet him last year gave me the motivation to replicate the bike that is engraved in my head. With the help from tons of people it's finally done! I bought this bike 6 months ago and immediately tore it down and started the restoration. DocWob had a full Ti kit for this bike along with NOS tag grips, rear sprocket and the...

4/9/2026 9:04pm What color was the smoke upon startup and did it only smoke the first time you started it after the rebuild? The leak jet only comes into play when you turn the throttle quickly. If you run through the gears and gradually increase the throttle does it run smooth? Do you have a manual for the bike? If so there...

4/8/2026 9:12pm It sounds like it might have a lean bog. If it had an air leak the bike would likely pop a lot on deceleration. You can put a smaller leak jet in the carb so that the accelerator pump squirts more fuel at the twist of the throttle. This sounds counter intuitive but a smaller leak jet forces more fuel...

3/30/2026 9:22pm For 700 bucks you could get your money back parting it out if the rebuild goes south. I would also budget the cost of a complete head just in case.

So after two and a half years of trucking this thing around for two moves, I finally got my garage set up (enough) and some time to get to tearing this thing down. Shockingly, the oil looks fresh. Could’ve been changed before it was put up, but a sigh of relief for sure since I was worried about the corrosion inside the frame tubes where oil is kept on these things. Same story with the coolant. Looks fresh like it was just changed before put up. The carb didn’t haven’t any debris either despite the air filter looking the way...

3/5/2026 8:34pm No I was talking about the inner bore of the connecting rod, the surface that touches the wrist pin. Just make sure the inner bore is smooth.

3/5/2026 8:16pm It is possible that all 4 valves are titanium but that would be very rare as it would be a very expensive setup. Usually only the intakes are titanium if anything. I think it is more likely that your valves are stainless or inconel. It is hard to tell from pictures what condition the cylinder is in but if there...

3/5/2026 7:35pm I dont see anything out of the ordinary. I'd check to see if the valves are magnetic. If they are steel the magnet will have a strong attraction, if stainless steel they will likely be very slightly magnetic, if the intakes are titanium they wont be magnetic at all. Pull the cylinder off and check the cross hatching and see...

3/5/2026 7:01pm Id change the shim to get the exhaust valve in spec and I think you will be ok.

3/5/2026 6:39pm Those clearances dont seem bad. What size shims are currently in the head? I would shim the exhaust valves and call it good for now. The intake valves are typically what go out of spec first since they were titanium from the factory, so the fact that they are still within spec is a good sign. Someone might have already...
