bought this cooling head from a friend,the only problem is he forgot what brand of cooling head it is..if i could remember it is an aftermarket head for the hyper 21 engine,but never had a chance to mount this head on my hyper21..good thing is that the hyper 21 and the go engines sleeve has the same size.

hey all - as far as the gotech .25 6port race goes, what pipe? is there a carb restrictor which gives the best of both worlds too?

I wanna know too!!!!

Well - first run of the season today..circuit all finished apart from a bit of rakin over on the new banked corner..MM stage 5 - 7port with 7mm insert ...da da da daaaaaah 10m36s on a tank for the first run..was a whisker hot for my liking and not smoking much so richened the hsn about 1/8 turn..perfect and 10m23s on a tank..more than enough power to spin the tyres just about anywhere on the dry loose surface and killing everybody else on the now longer straight. Rockin..really really pleased with this motor now its run in..still a bitch to start on the box without a little preheat from cold after almost 2 gallons.

For the .25 the Go 0801 or dynamite 086 and start with the 7mm restricter. Depending on track size and weight of the truggy you can go way smaller and you will definetly get the best of both worlds.

hi! there i need you guys help broke da go3r crankcase (cracked)& amainhbbs have no parts on this ,if you got spare even used one ,i dont care i just need to run again da truck, pls. just pm me if youre interested to sell it,thks again

If nobody responds call Russel at Racefactor Industries 1-928-274-4017 tell him I told you to call. He is the US importer so if no shop has it he might.

you could just look on ebay or look on racefactors website. Russel is a good guy and will deal with anyone. You don't need to mention anyones name for him to work with you. I'm sure he has what you are looking for

I use GO 0801 pipe with 7.5mm restrictor i get 08.50 minutes of runtime. Today i was helping a friend to end the break inn process and once leaned for race and 4 tanks in a row with stock carb no inserts was doing 08.00 minutes with JP2 pipe and Odonnel 97 plug. He will install 7.5mm restrictor so can manage to pit at 08.00

cya !

I'm running the stock .25 with OCM redline pipe (pretty much same as Novarossi 9853) with a shorter header from GO 2047. With standard 8mm restrictor and even the engine is not fully broken in yet I can do easily 8min in my OCM Truggy. Most probably I'll go to 7mm restrictor and 14t bell when it's settled and aim to 10min

has any one tried the MassiveMods Run In Ring? on a new engine.

also can someone point me in the right direction on how to disassemble a engine? take piston sleeve out that sort of thing. thanks for your time.

this might be listed already but whats the pipe of choice for the go tech 5 port engine ? it seems I saw somewhere someone said the dynamite 085, may be wrong. thanks.

Matt, you got PM
