    projected tip spark plugs

    As long as the pistion isn't hitting the electrode, are projected tip spark plugs are benefical compared to regular plugs? I assume it leads to better efficiency having the spark closer to the piston? This is for a Honda 200X three wheeler. Standard plug the D8EA and the projected tip the...

    1984 Honda 200X won't shift right

    My 84 200X, won't shift right. What happens is the shift lever feels flimsy and isn't catching any of the gears. When ever I try to shift up or down the lever won't come back to the center. Like I said it just flops around. When I'm riding, I can hit first gear, shift into second but when...

    Supertech 75W-90 syn. blend gear oil

    So, whats the scoop on Walmart's house brand 75W-90 syn. blend gear lube? The reason I ask is because I'm going to be driving from PA to FL this week so basically I'm trying to squeeze every drop of mileage out of my 02 S10 ZR2. PS. I already drained and refilled both axles with this stuff.

    synthetic gear oil for ZR2

    I recently bought a 2002 S10 ZR2 with 85,000 miles. I absolutely love this truck. I have never been a synthetic oil buff but recently I have been contemplating the idea of using syn gear lube in both my axles with hopes of gaining better fuel efficiency. To me, it seems like the areas within the...

    Cycle-RX question

    Is Cycle-RX a good way of trying to raise a bike's engine compression. Reason I ask is because my tired 1990 Honda CBR600F was dynoed only at 56.7 RWHP. I think a little may have to do with jetting but thats like a 20 HP drop since it came from the factory. Thats almost like losing a cylinder...

    oil for leaky valve seals

    Is there a particular brand of oil that is good for reducing the amount of smoke from having leaky valve seals? My 1991 S10 with the 4.3 TBI has the notorious leaky valve seals and every morning it puts out a good cloud of smoke for about 20 seconds. I've always ran Pennzoil 5W-30 since I bought...

    exhaust diameter question

    Here's my situation. I bought new Yoshi header for my 1990 CBR600F. The problem was, the collector was in a different location than the stock header. So I had a piece of pipe bent to make it fit with my Vance and Hines slip on muffler. Here is what I can't stop thinking about: The pipe used was...

    motorcycle ignition advancers

    Does anyone hear have or had experience with the Factory Pro ignition advancers for sportbikes? I am interested in picking one up for my 1990 CBR600F but I have read mixed reviews about them. I read that they are great and also read about how they take away HP at certain RPMs. My bike's timing...

    straight weight oil for Honda sportbike

    After seeing several UOAs that show just about all oils being sheared to the next grade down, I have thought about using a single weight oil instead of a multi-weight oil to help prevent this shearing effect. My bike is a 1990 Honda CBR 600F1 with roughly 24,000 miles on the odometer and a...

    Rotella 5W or 15W?

    So far I have been running RTS 5W-40 in my 1990 Honda CBR 600F1. From reading this oil seems to be very robust and after 1300 miles it seems to be holding up well. It seems like all oil ran in a motorcycle will shear down faster then an automobile due to the tranny. I've seen UOAs of Amsoil, the...

    1990 Honda CBR600F

    Can somebody recommend a high quality oil to run in my 1990 Honda CBR600F that I recently purchased. It has 23,000 miles on it and is unbelievably fast considering I upgraded from a 1974 Yamaha 650 cruiser. I was thinking Rotella 5w-40 or 15w-40? Is there any robust brands that are fairly cheap...

    GM 4.3L V6

    I have owned 2 1991 Chevy S10 4x4 pickups with this engine. Techniclly it is the GM 350 CI condensed down to a 262 CI V6. Both engines run great with and I am pleased with the power they can make. I have used Pennzoil conventional 5W-30 ever since I got the truck and it's what I've been using...

    1974 Yamaha TX650A

    Last summer I bought this summer and it has been really good to me. I've used valvoline 4stroke 20w-50 oil and 15w-40 HDEO rotella. Both oils worked great. But this bike has consumption issues. About every 500 miles it takes 1 quart. So I filled it with Valvoline VR1 SAE50 weight oil. I've...
