There are alot of questions on engine mods for street cafe bikes,so this is what you need.
A good chassis........Thats what you need.Upgrade your tires ,shocks,rims,spokes,chain,fork oil fork springs,brake up- grades.Seat, tank(optional).
Lightening your bike take the stock seat and exhaust off, the second half of the rear fender, the big old lights ,remove heavey steel lower pegs,bob up your fenders(not much weight but they are very long and look better bobbed (shortened) on the er of some splash protection if possible or deflection of rocks in face or motor.
Now put all these parts on a scale ,throw in the ape hangers as well.and you will see just how much horse power you have gained POWER to weight is performance, less weight, is the key.
Now you will add a light solo seat ,lighter bars,rearsets,new tires are better then anything the racers had in the day,maybe get some alloy wheels to replace the stock steel rims(if wallet provides)
Bob the front fender add some light small turnsignals that are brighter then stock.A new chain.Maybe you can fit larger dual discs or large twin leading shoe brakes,fit new brake parts anyway with new better material.
Any and all engine mods will reduce streetability,increase stumbling stalling,hard starting.
If you have a strong responsive lighter then factory chassis,Tires that grip to turn and stop better then new,then you can use all of the stock motor which is more then capable to get you around allday everyday.
Most racing groups make you run stock motors, get it! They know there is a lot of performance in the motor when you have brakes wheels, tires and a frame,rid of stock heavy parts,so can use all of the motor has to offer.
Its very NEWBIE to start on the engine when a very experience builder knows the chassis is where you start.Speed money wisely you will have a faster, bike, maybe faster then you can handle, if you build a high performance chassis FIRST.
Your bike will be worth more safer faster and a hell of alot more fun then a motor that you thought you were getting a fraction of a horse power maybe,and loosing a lot of horse power somewhere else.
You just dont read or listen to someones engine mod and try it on your bike you may have heard half the story.
Any engine mod is tested on track or dyno,its time consuming,expensive and requires tools and talent to carry out with great success and you are gaining somewhere AND LOOSING somewhere else! On a street motor that can make you a very fustrated rider.
getting your chassis as light as possible and as performance upgrades in tires wheels exhaust ,light seat,bob fenders, cost little, work everyday allday,make your bike look killer and your able to start and ride all day long is a true performance bike.
STOP IT WITH EVEN THINKING of engine MODS
These motors arent new they have miles on them your mods should be getting it back to as stock as you can .Set points and timing ,adjust timing chain.Look to see if carbs are leaking gas or taking in air where they shouldnt.grease lube everything is your throttle smouth or does it hang up some where is your chain fresh and adjusted have you checked your tire pressure.
Change the oil like a mad man old motors like fresh oil.
BUILD A GREAT CHASSIS you will go fast...and get a few racing rider training books twist of the wrist one and two.Your mind is the other motor that needs work on to go fast. The engine is done leave it alone!
Im so far behind ,that I think Im in first.
