drr 50 l/c 44" wide ???? stock or not

[aimo007]

I bought a new liquid cooled drx 50 that is 44" wide at the end of last year we ran a couple of local races and now I want to run states and every thing I read is saying that my quad is to wide to run 4-6 stock . My son is only 6 and only weights 46 lbs . What can I do , dont they sell -2 front rims or can I have them made and would it be legal please any info would help.

[jerkyboy]

Run him in the 50cc prodution class. Or buy new a-arms and rear
axle to make it 41". Id be willing to make a trade. I have a 41"
wide drx 50 that Im looking to make wider.

[Perazzimx14]

Used stock 41" a-arms can be had pretty inexpensively. I would hang onto the 44" a-arms in case you kid wants to move up to a different class.

[aimo007]

thanks for the help ... would that be legal I thougth I wasnt supposed to change anything ???

[jerkyboy]

If you don't want anyone to know here is not the place to
ask. LOL!!! If you don't tell anyone where you race. There is no real way they could tell since everything else is identical.

[quad1rider]

actually you can change them and tell everyone the drr44 wide is an option and chaging it to oem 41 is fine the issue your confusing is you cannot down size a 70cc to become a 50cc quad this was ruled illegal... like the 70 Apex to a 50cc...

problem is if the rims are set up as to turn them IE 2-5 like the new 50 Apex you would not have a problem but i think those rims are Oem 4-3 which will make it illegal to change the rims... and still be legal... solution is changing the arms the quads stock axle on the 44's where not changed so you need not worry there..

if your son is 6 then he is elijable for the 70cc class also and the 44 wide could be bumped up to a 70 very easily,

Is it true that if the manufacturer produces a quad with 41" a arms and 44" on the same model it is legal to make the change to 41" since it is a production spec? I would think the same would go for the carb as the 50 DRX has been made with several different carb sizes throughout production. Can anyone clarify this for me? I added to this thread since it was along the same line of subject.

T-BONE.....very good ?????? i would like to know the answer also....

[tireman43]

The answer as I have been told is...If it is an option of the same model YEAR, then it can be changed. You can't take an 04 single a-arm and make it a dual a-arm bike and same for the 44"-41". If it was an option that year then yes you can change it. Same goes for the carb. If it was an option in your year for different carbs then it's o.k to change.

Anyone know what carbs have been offered on the 08 WC DRX 50?

[quad1rider]

I believe that would be the sun and oko for 08 the sun is definately better but it wasnt offered in 2007 so it cant be used on an 07.. the mukuni was used at one point as well but I dont recall if it was 06...

I wish they would allow the upgrade issue to be used as an option they we could all run the PE20 but that would eliminate the oil injection... which wouldnt be a bad idea either.... but that might have to do with the pollution emission...

[hotquads1]

the mukuni was stock in 06" and some 07" , the 21 OKO has come on some 07's and some 08's , sunworlds on some 08's. The mukuni was a good carb also can be tuned for good results. The rules state you can run any carb that was factory installed during that model year, this is for stock limited class other classes are not held to this rule. If anyone needs further info on this matter they may call me , I will be glad to help .

Thanks, what model Mukuni was on the 08 DRX 50 model?

[hotquads1]

none on 08" models

[#17TBoneRacing]

I guess I have to stick with the Sun or try my luck with the OKO.

[hotquads1]

the sunworld is very good( copy of the mukuni) , just needs to be tuned in, I would skip on the OKO.

My only concern is the size. Is a 16mm large enough? Mine seems to run good, but wanted to get the full potential of the motor. Any thoughts?

[hotquads1]

yes it is large enough , for years the DRR 90cc came with the 16mm carb.

[#17TBoneRacing]

What mods can be done to the Sun 16MM and will keep it reliable?

[hotquads1]

call me sometime

[quad1rider]

Hey tbone I thought you was running stock,,,,???everything you have asked and questioned has been keeping to the stock quad or at least that is what it seems but then you want to modify stuff that is stock and that would not longer be legal so you might as well switch to the PE24 keihin and do the other mods too... the keihin is superior over all those carbs...

[#17TBoneRacing]

He is running stock. I was not sure what options I had to remain stock and get the most out of the carb. It looks like the most reliable way will be to keep the Sunworld and dial it in. The quad seems to runs great now, but wanted to know what could be done to dial it in and remain legal in the stock class. By no means would I ever consider not staying within the rules of the stock class, nor do I have endless funds to throw at the bike. If it means a couple hundred for a new carb and needed accessories or another similarly priced mod I would hardly consider that excessive. I believe that developing the rider is one of the biggest "mods" and the best "investment" you can make. For us it is not all about winning, but rather the family time together and enjoying what we both share an interest in. Winning is only gravy on the potatoes. At the end of the day it's all about the fun and experience gained.

TBone give Marc at Hot Quads a call and he will point you where you need to be, as he mentioned. He also happens to know the rules very well. If you dial in the Sunworld carb it will work great. It's not always bigger is better.
