I read a lot about.should I buy a 200 beta trials or a 300.
The beta 125 weighs the same as a 300.yes they feel different.but the throttle works both ways off and on.the 125 is 12 bhp the 300 is maybe 20 bhp even poss 22 bhp.its nothing. It's not like a yamaha r1 compared to
Just changed the dog bones on my evo 250. Came with bearings and inserts. Now have nearly no play in rear suspension.well happy. I did change the bearings before.but this is a much better job. And an easy fix.
Will order a new delta linkage the original feels slightly worn on the swing arm pivot.
i have 2 betas a 125 rev 3 and 250 evo. The 125 feels like a bicycle to ride yet same weight. Allegedly it's reciprocal mass of piston that makes 250 feel heavier.250 prob has 16bhp. 125 about 12bhp.not a lot of difference.
It disappeared past rings. Today have changed piston and rings.took a chance with b piston. Compression much higher. Piston underside and crank was covered in oil.
Think that's why I thought it was running rich.will change oil seals this weekend.
I'm changing the pilot jet, bike came with a 45, the plug oils up,so tried a 40, it ran lumpy till I got on main jet, put in a 38, now looking at a 35. Is it normal to have this size pilot jet,???
With the 40 it pulled the front wheel up off the throttle, but lumpy.
New plug in it, bpr7, also tried bpr5, still oiling up, have repacked exhaust and cleaned it out,
Checked the float height by blowing gently down the carb fuel inlet, what a great way of getting it perfect, can't claim its my idea, so, the chugging was not float height it was pilot jet too big, new carb had a 48, changed to 35, prob settle on a 40.

I brought it cheap, 1500 quid, have cleaned it up. changed linkage and swing arm bearings and it's now perfect, have played with the jetting it's now, got plenty of poke, will climb anything and is reliable, the factory has decent suspension both ends, I only buy beta, I find them easy to work on reliable and parts good price,
People say the clutch drags, I put a very thin washer behind the pressure plate and it never sticks,
Coming from enduro you know about maintenance,
I thought tyres are pricey, till I remembered I paid £70 for a rear michelin in the 80s,lol
Got same bike cheap money, same condition, rear brake was rubbish,so galfer disc and pads, now perfect, swing arm bearings not that easy to replace but now done,
Got new wheel bearings to fit next, easy job ?????
Had the rev3 125 a couple of years, done a bit of work on it, then got a 2011 evo factory in poor condition,
Have cleaned it up, changed swingarm bearings and linkage bearings,now near perfect, one thing I will never do is use a power washer on either,they rot everything,
Used the 125 last weekend and forgot how easy it is to ride,feels lighter than the 250, but it's not,
One change I made to 250, slow throttle,its now so much easier to ride, joined the North hants club, its been great,
Start it up with clutch pulled in, warm it up with clutch pulled in, it clears very soon, I have rev3 125, and evo 250, 250 has a thin washer behind the pressure plate ,an easy mod.
Paid 1500 for evo factory 250, 2010, have cleaned it, changed some parts, cleaned all the frame, swingarm stickers off, looks great now, stands me in 1800, and is something I will keep and work on for years, I use it in local club trials plus ridgeway, so a good buy, with a strong engine.
Held rear wheel on my evo 250, and shook bike, felt like the frame was cracked, looked at shock linkage,there is a lot of play, ordered new bearing kit, which is extensive, will fit kit within an hour, then feel bike will be perfect.
