Hi all just after some information on his how much it will cost to have a complete rb20 motor built I already have a complete dl 125 engine running in my dl just need more power

[LI150]

A lot of money is the short answer.

Kit £400 ish
Crank £200 plus
Decent carb £150 plus
Exhaust £250 plus
Clutch £200 plus
Gearing, seals bearings etc.
£30 to £40 per hour labour
Decent disk brake £250 plus

If you haven't got £1500 in the bank i wouldn't start the build. As stated the major parts cost quite a bit but i found with my Avanti build it was the little bits that took me over "budget".

the budget also depends where you source your parts and the quality you feel you need. The difference between the top-end parts and the budget parts is probably more than double (both price and quality)....

[Aaron.c]

Yeah that doesn't seem to bad budget would be about 1700

if you already have quality parts like the clutch, brakes and bearings then your on your way. you can also save quite a bit buying cheaper second hand ancillary parts like the exhaust and carb. As far as the kits concerned id buy new off AF.
like all hi spec kits they have the ability to eat money and things easy get out of hand if you go by the 'buy cheap by twice' mantra....

Also you can use your existing gearbox with 19 x 46 sprockets
good combination

In my RB20 i ended up with a SIL crank (after going through two af ones ) with a 115 rod ( this requires 1mm taken of the bottom of the barrel) great cheap crank and with 19/47 GP2 box a std 4 plate with strong springs is capable of handling the power (20bhp) keeps the cost down

Electrics???

standard 12 volt Indian will do the job, I have had both those and expensive ones pack up. This is one place where I'm not sure if more money spent necessarily guarantees longer life/quality.

I've just finished an RB20 build and I've spent close to £1300. I already had a gearbox, carb, rear hub, brake shoes, flywheel cowl, gear linkages, chain, chain tensioner and various internal and external fixings. I'd imagine you could throw another £500+ on top for those bits and bobs. It's not a cheap hobby this scootering malarkey is it?
