Hi guys ! Me and a friend of mine are in process of building a big bore out of an RXG. This is the first time I will be trying this out and I am pretty clueless about it. I know that there are a few guys here like Sunny (Sunmysore ) who have big bore setups so am looking for inputs from guys like you. Right now I have this vague idea of procuring a DT200 piston. The plan is to take the 132cc to 170cc. I have also heard of people using 65mm wiseco piston but our budget does not permit that - plus I am not a big fan of wisecos.
The project bike is an RXG with a 5 speed gearbox , stock electricals , stock airbox and a slightly port polished 4 speed bore on 1.25 oversize with a nice chamber. Since it would be difficult to procure original ART or even Goetze ( not Godzilla ) in 1.5 OS, we are thinking of getting a big bad piston and shoving it in :P
The plan is to get a bigger & better piston to take it to around 165cc - 170cc , port the bore , get a bigger carb on - maybe a Flatie or Kehien D slide. Cycle part plans are to run 17 inch alloys on R15 rubbers. Target power is huge amount on torque - a powerband that starts off early without a big flatspot before a violent powerband kicks in - do not want something too peaky but with all round power. The hope is that it will be a wheelie monster in the first three gears. I will be posting pics of our project once we start by next week. Will need you guys advise on pistons , connecting rods - and your own experiences with your big bore setups.
I own a nice street port RX myself. My setup is a mix n match one. It is 2003 model 4 speed - running a ported 4 speed bore , 5 speed malaysian close ratio transmission , a worked 5 speed head and a chamber on a Stock carb and airbox on 90/100 electricals. Its a little peaky - and the front comes up in the 1st two gears - I have alot of fun on it. I hope that the big bore that we build will be twice as much as fun !! Looking forward to your inputs on parts, tips and what expect from this ! Thanx guys !
