Guys,
This is for a friend in Peru.
He is using a DM SPEC with offroad .21 engine.
The thing is that, based on what he is explaining me, it seems that the 2 speed setting springs get warm/hot and softer after couple minutes of run so at start the shifting point seems perfect but after couple minutes it starts to shift early and early as the springs gets softer ...
Any tip to solve this ??
thanks in advance guys ...

IF you are rich, the motor takes longer to get to the RPM to make it shift...So as the car warms up my shift point is too slow...as the car comes up to temp at say, 170 degrees... the car shifts perfect. In short, make sure you are at operating temp before you make adjustments.
there is a hole in the 2nd speed clutch bell rotaate the shaft until you see the set srews,(2) back both off EVENLY..SMALL amounts.. VERY SMALL... Turn in to make is shift later, Out to make it shift earlier....
I hope this makes sense.. I am sure there is a Youtube Movie about this someplace...

Keep in mind that the tune on the motor will change the shift point as well.

Im clear about all you posted, and thanks ... but the thing is that, there exist some harder adjustment springs ? ... i think that the stock ones, tend to get softer after 15 minutes of racing ...

There are aftermarket springs and chutch shoes (Aluminum).... I have not used either as of yet.. I am new to the car as well...so I am still on the stock ones... We tested for 30 min straight last weekend.. Just to check tires and temps.... the car seemed fine.. But our track is very large and it not shifting as much as you might think... maybe 6-8 times a lap..
Good luck... share what you find out..I am interested to hear the feedback.

If after a couple of minutes your shifting early, it's because the engine has warmed up and running leaner than when you started. Set the shift point after after the engine tune is consistent (during practice of course.)

I also notice that the shift point seems to change the longer I run.. Mine actually seems perfect earlier rather than later - so once I'm at 250F or so it's shifting too early.. At 200ish or even cooler it's perfect.. Could this lead to problems with shredding spur-gears or CB bearings?

If its not a tuning problem, check the size of the springs against new ones, maybe they're wore out or have lost spring tension. Just another idea to check. good luck

Thanks ... as this is for a friend i preferred to come here and share the query.
Im pretty sure is not a engine tuning related issue, is only about the 2 speed systems, specifically on springs ...
Jeff, do you know if exist some other source for this little springs that are more resistant to temps ? ...
thanks !
