I have contacted the mugen distributor here in Australia and he said this has happened to others and believes that if you tighten the spring all the way down on the engine clutch and than back it off one full turn than that should fix the problem, but I was at 1.5 turns and I am still stripping gears I will tighten all the way and see what happens. P.S this was happening on both Mugen and 3racing gears.

Use C0111C ball connectors to increase the height of rear stabiliser.
Add 0.3 shim between bearing and 2nd speed clutch on the main shaft.
Replace 3x8mm screws with 3x12mm for rear bulkheads.
Replace rear bulkheads, spur gears, pinion gears with new parts.
Rebuild your flywheel outwards.
Follow the instructions for clutch setting from the manual. I guess is 0.7mm tension gap.

I would not recommend inverting the shocks as this increases the unsprung mass of the car (ie. suspension weight), as a result of the shock bodies being supported by the suspension arms. I believe that Josh Cyrul has experimented with inverting shocks, with limited success. A titanium upper screw set, brass battery receptacle or replacing steel components with titanium equivalents (ie. pillow balls, etc) are better alternatives to reduce weight in optimum areas of the car.
Hope this helps,
Jack

Racer-Oz, I think that you should go with this pipe.
It works really good.
No I tried a differnt one this weekend, and going back to the Mugen Pipe.
Some people like the Skylline pipe.

There is a slight slop on the main shaft side to side. Some shims before putting on the 2-speed shoes will help. Here is what helped me solve my 2nd gear spurs from getting chewed up ....

I pulled off the spurs and then the 2-speed shoes. I noticed on the shoes that there were rubbing marks from the stock engine brace. The brace actually does hang over about .5mm. What I noticed even more was that the wear on the shoes was more apparent where the two shoes butt up together. So when it splits apart, the corner is hanging and banging up on the brace.
So this is how it goes:
- engine revs up and kicks in 1st gear. All is fine with one-way bearing.
- car starts to kick into second, 2-shoe splits apart to grap 2nd gear spur. The gap starts knocking engine brace corner and cause momentary stalls. But since there is no free spin for 2nd gear since it's engaged, the pinion starts chewing away. I also pulled the 2-shoe clutch apart by hand, and I noticed that it can wobble side to side a little. This may also help in catching the brace corner.
Once again, this is only my theory. I have yet to test since I'm waiting for more spurs and pinions.
But if anyone else is having this problem, could you check your 2-speed clutch shoes and stock engine brace for wear? I figure if you just simply grind down the brace on both ends, just in case you flipped it around, you should be fine.

Now that is interesting. The Old Gears. Wonder what the Ratios' work out to be. Hummmmmmm. Have to check that out. Sounds like a good Idea. Anyone know the internal off top of head. Pretty easy to figure out.
