Hey guys have just finished breaking in my JS23R, i have pulled the head off just to have a look at things and noticed that there was two aluminium shims but no brass shims! is this normal? I have a JS21 as well, which had one aluminium and two brass shims, and we removed one of the brass shims which realy helped with tune and performance and was going to try the same with the 23R, any info would be greatly appreciated.
Cheers
Scott

Stock JS .23 has three aluminum shims. Two 0.2mm and One 0.3mm. Here in the US we run the two 0.2mm shims. Total 0.4mm in shims
Stock JS .21 - In the US we remove the aluminum shim and only run the two cooper shims. Both these shims equal the one aluminum, which is 0.3mm

I run 30% nitro, what do you suggest I take out.

Hi Ed, I have just looked at my stock .21 and it has three copper and one aluminum shims. I have not changed them since having the engine. I purchased it here in New Zealand which might explain why. One of the copper shims is thicker then the other two copper shims but not as thick as the aluminum one.
I run 30% nitro, what do you suggest I take out.
Regards,
Gerard.

the thicker copper shim should be 0.2mm and the thinner should be 0.1mm, not sure about the ally one, but i would say you could just use the copper ones as they should shim to 0.3mm. Cheers

Hey guys also i need a EFRA pipe to run on my JS23R, as i dont think the 086 is EFRA approved, i have a HongNor 2047 EFRA pipe which is a top end pipe and a OS 2060, would one of these work ok? or are there any other suggestions?
Cheers

Does the "race ready" JS .21 still come with the aluminum shim and the two copper shims? I just wanted to check with everyone before I pulled the head off my relatively new "race ready" JS engine to remove the aluminum shim as Ed suggested.
Thanks

Hi Gerard, yes definatley remove the shims that Ed has suggested, we had lots of tuning issues with our 21s untill we removed shims, and they also perform a lot better as well, and we also run 30% nitro, give it a try

I've driven the A8 buggy a number of times and my impression is that it is a VERY touchy and unforgiving buggy to drive. I'm a decent driver, but it seems like this buggy was set up to be driven only by top professional drivers and any little mistake you may make, it makes you pay - in a hard way. It might be just the actual buggies I've driven (they were all Agama factory driver's cars, including Gene's, and he can still hang with some of the best in the world on the racetrack), so I'd actually like to get an opinion on the buggy from someone outside our little Florida circle.
Thanks

Nice! How do you like the Agama? I'm good friends with Gene Hickerson, the US distributor of Agama and VP Pro and he's asked a few times for me to switch over from my Losi's to the A8 buggy and their soon to be released truggy.
