Maintenance and Tuning for Sports Bikes and Dirt Bikes.

Chain and Sprocket Wear

This is so frustrating to see and could be total avoided by a simple maintenance program of oiling the chain. See, if you oil it correctly it should never need adjusting - if it does need adjusting then it's wearing because of lack of oil or just straight out abuse. Don't wait until it's dry before oiling it, oil it regularly before it gets dry and this won't happen, and the bike will ride so much smoother. 

It's not just chain and sprockets that are getting hammered here, there's wheels bearings, swingarm bearings, gearbox......you can't afford not to look after these things. Left much longer and this chain would have broken. Come on people this is simple stuff!

Too Much is Never Enough

Well, sometimes it is...

Someone forgot to tell this bloke you need to remove the old oil before you refill it with new oil.
It ended up with over 6 liters of oil and I was shocked and surprised to find it blowing blue smoke on the dyno and less than 75 horse power to begin with. I honestly thought something had let go until I discovered how much oil came out of it.
We had to pull out the air box and to drain the oil out of it, replace the air filter and of cause refill it with the correct amount of oil "3 liters"

New v's Old Chain and Sprockets

Look at the red line in the graph and note that it's very jagged.

This is because the chain has tight spots, meaning if you put the bike on a stand and spin the back wheel checking the chain tension as you go in some places its really loose and others tight. If it does that to the graph I wonder what its doing to wheel bearings, swingarm bearings and even worse gearbox final drive bearings. The most common cause is a total lack or irregular oiling and maintaining.

Yamaha R1 with Faulty Exup

Heres what happens when the exup valve stops working correctly. It could be a broken cable, seized valve or something jamming it or an electrical fault. The cause of this one was that the servo motor was not opening the valve fully, hence the first part of the rev range is fine but as the revs creep up the power starts to drop off. Fixing this relatively minor fault resulted in an extra 30 horsepower!

By the way, this bike has 165,000 km on the clock, original engine. Shows you what you can expect with regular servicing and some basic maintenance.

Suzuki GSX750ESD

Working on older bikes can be very frustrating. The problem with this one was that it runs fine until you hit the highway and cruse at 100 km for 5- minutes then it would feel like it was running out of fuel. We couldn't simulate his problem on the dyno, however at the owners request we did tune it because it was very rich and this may have been causing the plugs to foul at 100 km. That didn't fix it!@#$%^^&

After a number of road tests we discovered the problem was turbulence creating a low pressure area around the intake snorkel caused by the seat buckling and leaving a gap, as shown above, when sitting on the bike. As soon as we taped up the gap the problem went away.

Simple to fix..... really frustrating and time consuming to find.
