The new company is just making engines, If you want the Radical buggy or barts you have to look into the TQ Racing SX8, its the same car.

Hey Dave, Do you guys ship to Australia??

glad to see these mills back in action! A buddy of mine had one and it ripped big time...very, very strong motor and ran cool and idled all day long..he had big issues with the HSN assembly though (you could bottom the HSN all the way in and it would still run pig rich and no amount of tuning on the low end would help).....any word if this new run of Radicals has that issue corrected??

That was very small batch of engines, the high speed needle seat was drilled wrong. We were replacing all of the defective ones free of charge. Like I said it was a small batch so not many were out there, but a few did make there way to the shops.

that is good to hear...aside from the radical pipe, what other pipes run well on the 621T? If I recall, we changed out the Radical pipe to a JP2 on my buddy's 621T and it was very strong in his buggy...I may need to look at picking one up for my strr

Can you let me know if you have a piston & rod in stock and do you know if it will fit the OPS SFV21B if so can you pm me with the info thanks

i have a o.s max -cz- engine ive looked all over the net can anybody tell me what size it is its not marked on it any help would b great thanks

Probably a .12. Maybe a .15. Why are you posting this question in the Radical Engines thread? You realy oughta start a new thread for discussion of your OS engine. Radical is a brand name, not an adjective in this case....

How many people are currently running Radical engines in the USA?

Me 2 of them

I have a couple of them. very fast motor I must say.

I just put in cermic bearings in mine

where can you buy these motors?
