baja minibike engine dies when under load

[gvfc2]

Didnt get a chance to buy in yet. No money. But i soon will

 

[gvfc2]

Well cant ride it on my street no more. Cops showed up and gave me a warning. Need to find some place to ride it now. But time to put it on brake and make some money to upgrade it

bummer... i used to ride on my street for over a year until the new lady moves in and calls the cops on me the first time she sees me. i havent even been able to ride my doodlebug 20 feet without having to stop yet. do any of your friends have dirt bikes, go karts, etc? get together and find a place to ride! someones gotta have a big enough yard

 

[gvfc2]

I wish i had some friends. but i will get together with someone after i upgrade the engine

mini bike

Just realized I posted in wrong section. Instead of making extra work for the mods. I'm turning this into a well here's my project

Your first problem is you went with the 99cc....harbor frieght 212cc predator engine is a deal and on sale for just about $100......I also have baja warrior mini and it performs!!

 

[gvfc2]

Well my first problem was i bought the bike and havnt done any mods to it. I havnt bought a new engine for it yet. I am going to go with a 212cc predator. But also got a crazy idea for a 125cc lifan dirtbike i have. Has anyone put a dirtbike engine on a doodle bug?

 

[Jcotz]

I have never seen anyone do that myself, but you would get some crazy speed and power. For me, it would probably be too scary. I don't know about you though.

 

[Doc Sprocket]

Yes I did. Took the tire off the rim and had an inner tube I was able to cut up and used some rtv silicon and sandwiched the rtv between the inner tube and the tire where the hole was and it stopped leaking

Ahh- I see. was the tube leaking too, or just a hole in the tire? I hope you cleaned the heck outta the inside of the tire first for the best chance of adhesion.

 

[gvfc2]

i didnt really clean the inside. just used some wet sandpaper thats meantbe dry and some alcohol. the tire is tubeless so it was just the tire that had the leak. what it does is just hold it there while the air pressure pushes it out.

on a side note. my phones 3g is slow for tethering

if your tire goes flat again i would recommend a slime tire plug kit. their at walmart for $3.00 plus tax and are used to plug atv tires.

 

[gvfc2]

Well i only did it till i can afford another tire. Its actually completely bold

 

[gvfc2]

The engine that came with bike i noticed the blower really doesnt serve a purpose. There is no forced air there is absolutely no way for the air to get to the air intake. Woukd be wise after finding this out to take of the fins or better to leave it as is? Also would i be able to leave the shroud off it has no openings for air to move to intake

 

[gvfc2]

well as promised awhile ago here are some pics

 

[gvfc2]

today i did some work. i tore it all apart to prep for paint. going with a hunter green. (its the only color i have right now) later im going to repaint it not sure what color tho. the pvc pipe on the air intake is for the ram-air intake. just took of the main part to take it off the frame

 

[Bluethunder3320]

clean bike! wheres the throttle? lol

 

[gvfc2]

haha there really isnt any. i have to finger the valve on the carb for any type of throttle.

 

[gvfc2]

ok so painting is almost complete. just need to pay the forks. looks better than the doodle bug green IMO. want some pics of the new color?

how can i make the wheel bearings have little drag?

 

[Bluethunder3320]

are the bearings dragging? they are supposed to spin with almost no friction

 

[gvfc2]

when i let off the throttle i feel intant slow down. so much so i go forward in the seat alittle

 

[B man]

check your brakes. and if not. test your bearings
