If they are testing parts, they will ride the exact same lines each lap to try and notice the differences the part makes. They can't tell what's going on if they are switching lines up every corner and not getting a consistant feel for what the bike is doing. Like jndmx said, aside from testing, the rest of their time...

Women seem to find it attractive when they come over and see an engine completely torn down and layed out and to be able to explain to them all the parts and how they work lol. You're right through, the average american man in current time has very little mechnical inclination. And i'm not even talking rebuilding an engine. I'm...

Yea you need a special tool to remove that. Don't try to knock it loose with a punch and hammer it won't work. You can get one at pit posse. http://pitposse.com/47crsereto.html

It's no different technology than any current models that run a nitrogen filled shock. A nitrogen tank setup does not cost very much money. You can build a 1 gallon setup for about $100, which holds enough volume for about 30-40 shock charges. The nitrogen costs about $25 per tank fill. So basically, for almost the cost of a new...

Very interesting to see the direction Showa is taking with their fork development. They have made two large improvements in just the last year with the SFF and now the "air fork." I was most impressed with the idea that the heavier fork goes on the side away from the caliper to neutralize the weight. I can see where that...

It probably wouldn't start right if the valves were too tight. Did the mechanic cut new valve seats on the valves that were replaced? The issues are kind of baffling me because they are conflicting. If the bike ran poorly from the time you started it, I would say it's carb issues. But when it runs good at first and...

You're actually fairly wrong. For my senior research paper during my engineering studies, I chose to research testing procedures for advanced composites and polymers, which included a section about the testing methods of helmet safety ratings (always had to figure out some way to involve motorcycles with my college classes!) You see, it turns out every test HAS to be...

Most stations have stopped selling 93 octane because of the blend with ethanol. your easiest bet is going to be 91 octane and then use a quality octane booster. Although you shouldn't need 93 or octane booster. Most bikes will run fine on fresh 91 octance pump gas. You shouldn't need anything higher unless you've got a mod engine with...

There's a alot bigger difference between a few hundred dollars between the trade-in value and private sell value. If the dealership buys your bike, they are probably going to price it on their used showfloor over the high price given by KBB or NADA. This gives them the wiggle room to "knock $500 off" or "throw in that helmet" with...

x2. I bet there's alot of Pro series riders out there taking a couple weeks off for vacation and rest right now, maybe doing a little bit of testing or maybe doing a special race here and there. But stewart isn't fitting the "perfect model" right now and wow... Everyone bitched because Stewart wouldn't pick a ride or a team...

I don't know about you guys but why they hell wouldn't he want to drive/race late models when he can fit them in? I know I would...and if i had the finances I would go race late models anytime but that sport is just so dam expensive. I think late model racing would be about the most fun you could...

You need to drop your leak jet way down and try adjusting your acc. pump timing or wire it closed (this is what alot of the Yamaha guys do with their carbs) so it is no freeplay or delay in the fuel injection. Most of the issue is the leak jet though. Get that down to the right size and...

Simple green is the best way to go. Buy the concentrate and mix it 50/50 with water to make it stronger than the premixed bottles you buy. spray off all the mud first before you apply the cleaner and then let it "soak" for 2-3 minutes so it can penetrate before you do a final rinse. There are some other...

X2. revised porting. cylinder will directly bolt on.

I had a axle stuck so bad one time that I had to take the whole swingarm off the bike with the wheel attached and I had to use a press to push the axle through. If it's stuck that bad, I don't think you're going to get it by trying to hit it, plus you are probably going to...
