Way too much power for the kid

First of all, I'd like to extend my most heartfelt salutations to the members and moderators. This is a great resource/community.(ok 'nuff kissin up)

I bought a DR350 figuring that it would be easier to choke off some horsepower than it would be to invest in a smaller bike and build it up. He's plenty big enough to handle the weight (he outgrew my shoes at 14), I just don't trust his judgement with all that horsepower.

What are some ways this can be done with a future restoration back to stock in mind. I was thinking under carburetion but that would require rejetting, wouldn't it? Any other ideas?

thnx n happy trails

Throttle stop is probably the easiest way if you can do it cleanly. You could also come up with a restrictor plate, but that'll have some consequences beyond just a reduction of power which could be difficult to sort.

So he's over 14, and it's only a DR350 - just let him get on with it. No teenage lad is going to want to ride around with a throttle stop keeping it from opening fully, and it's a gentle bike anyway. Don't worry about it.

don't worry, when i was 14 i rode a 1994 Cr-500. Not that i could handle it but i could ride it!

So the advice is too restrict the kid, not the bike. You could put some really tall sprockets on it and reduce the top speed.

I really appreciate the input. I'll consider just turning him loose on it, but I gotta be honest, with myself just getting back into riding again after a 10 yr hiatus, he's never even been around it to see how to behave with a bike (at least not that he can remember). I think the throttle stop has merit and I'm fairly certain that I can fab one up easy. I really like changing the gearing. We'll see how it goes. I guess a broken bone never killed anyone and chicks dig scars right? :ride:

thnx n happy trails!

Errr.... not to put the Fear into you or anything but I promise that statement ain't true. Femoral artery bleed out?


cut a short piece of plastic tubing and put it over the end of the throttle cable before you put the cable back into the carb slide. Slide can't go all the way up, no brackets to fab, easy to adjust or remove.

I did just that to my sons CR 80, but i took a thin alloyplate and cut it to about 12mm and put it on top of the throttle. Worked perfect!

OK... everyone is differnt... but since it's a dirt bike... let him learn respect for the bike. Make sure he has good riding gear on... and let him crash. It's a dangerous sport, and you WILL go down eventually. Beside... a DR350 isn't that hot of a bike. I think they make about 25 HP.

at 14 I had been riding for 6 years already, and I was running a PE400 (2 stroke) in open desert enduro's.

I've been down countless times in the dirt. (and a few times on the street) I've broken helmets, frames, sub-frames, forks and miscellaneous body parts. All I can say is... it's going to happen.

      Hi Guys,
      So I recently bought a 1997 XR400. I've done some research into getting more power through some basic mods and rejetting the carbs. Though all of the ones I've found have been for post 98 XR400s so the stock carb set up is a lot different. Usually people are opening up the airbox, exhaust ect. ect. and Jetting their carbs up to 160/162 for mains around 60 ish (I think) for the pilot. However for the 97 model this is close to stock for the jets.
      So essentially what Im asking (Just to cut to the chase ) Has anyone got a 96/97 (maybe 98, not sure) XR400 and has done these similar mods, and what sort of jetting have to done as a result.
      Thanks in advanced, also its my first post so apologies if I havent done everything correctly.

      38MM Cast SmartCarb. Purchased a couple years ago for a yz250. Don't have the bike anymore, and it has been sitting around for about a year. Used, but in fine working condition. You can also purchase a different needle for different bikes, as well as rebuild kits from their website.
      Asking $250 shipped to continental United States. I can arrange other shipping options at the buyers expense.

      Hey guys I just bought a bike last night. So the seller said the bike will turn on but then die. We didn't try it because it was really late at night and it was raining (seat was wet). But he said if you bump start it, it will turn on and ride. So what do you think the problem is? I just want to make sure it runs... I probably won't be able to bump start it till Saturday (rain)... It's a four stroke, and I know absolutely nothing about them. Thanks.

      I know this topic has been discussed in the past, but I have not found any options available for the new 2018 bikes. I live and work for a new Beta Dealer (Auburn Extreme Powersports) in California, and we are having a difficult time mapping the RR-S bikes for full FMF exhausts. We have tried contacting Beta Support several times for this issue to no avail, and we typically are given the runaround when transferring to techs and secretaries. From what we can gather, the FMF flash is designed for the RR bikes, but not the street-legal counterparts. Every time we try to install the FMF map onto an RR-S errors occur, and the programmer screen goes virtually blank. We have heard through the grapevine that some are using the RR maps on the RR-S with success, but we have yet to try it, even on our own bikes for fear that it will permanently erase or damage the CDI. Any and all help or suggestions regarding this topic would surely be appreciated! Thanks, Ben.
