Have you tried sanding the zinc/chrome plating off with some coarse w&d kurt?

I' watched some vids on youtube that said to use the green course side of a washing up sponge, ive tried that and it did next to nothing, i did get one working bhut then the CDI fried itself and I was a bit concerned that it was maybe because the A123 cells had overcharged it, so i went back to a normal lead acid till i sorted it all out.

As it turned out it was nothing to do with the A123 cells but i just havent bothered to go back to them again because of the hassle of sorting a charger for them.

I'll give them a go with some course W&D and see though, cant do any worse than I already have done!!!

Doubt that the green side of a pad would do a great deal to the plating.

Ive in general soldering only likes tin and copper to bond to sucessfully however abrasing the surface to create pits for the flux and solder to bond could be the solution.

Good Luck

I never had a problem with total lose on my trackbikes and i never did that many trackdays a year so they wasn't in regular use. If i remembered then every saturday id turn the battery charger/optimiser on, leave it on for the day and that was it. I always took the battery from my roadbike with me just incase but i dont recall ever having to use it although i was paranoid and after every session plugged it in to the charger.

Yeah its this bit that will cause all the hassle, I'm pretty sure it'll be ok to run all day on a fully charged battery, but I'll still panic about it between sessions!!!

Cheers for the advice with the soldering Rick I'll give it another bash!

With the useage of oil, I've been thinking, my bike never gets that hot when im using it 70 at most to be honest, if the rings aren't getting fully up to temp could this be causing a bit of blowby as they arent hot and expanded as much as they could be??

Might try a couple strips of duct tap on the rad to get it running hotter when in use??

An NC that doesn't run hot! you wanna hold on to that one mate lol

Isn't 80 ish the ideal running temp? you could well be right with that theory so yes some tape over the rad will help, might wanna check your temp gauge is working right first tho.

Yeah good point about checking the temp gauge as the frame rails get pretty warm, the gauge does get around to 90ish when I'm warming it up on the stands, but it could be reading inaccurate, hows best to check??

Just get another gauge and see if it reads the same?? or can i remove my current gauge and test it in water somehow??

pretty sure there is a temp gauge test in th Haynes Book of Lies.

I'd tape it up a bit - 70 is too low, it will run richer at cooler temps = less power...

my chinese rads from Geoff are ace - no9 has no fan and i;ve been out a good few times of late and it has never been above 80. I might have to get some tape on them or figure something out to regulate it better

It went well, I had a really good time and my times improved a lot, I took 7.5 seconds out of my best on Friday, this wasn’t solely down to the lack of a flywheel and stator, but it really did help contribute to it.

The bike just gets into its stride a lot quicker which helps it to make its horsepower in a shorter section of track, it also allows you to be able to run a higher gear around a section of track and allow for the revs to fall a little lower as the bike will have the additional ability to pick up from lower down as it hasn’t got as much weight to spin up so will pull from lower down the rev range.

I also found it didn’t help my or hinder my starts, these I think are good anyway and they were no different at weekend, the only thing I noticed was that the front will just paw the air as you go, this may be that I was attacking the starts a bit harder than previously though! after all, at the end of the weekend I have still only done 4 gridded race starts so I will be changing/developing my technique and it will not only be the bike which has changed. I am a total and utter fanny into and out of the first corner but that’s a different story.

I also lose a lot of time on the first lap farting around settling in, then spend the next 7 laps catching back up. Which is annoying……………………really annoying!!!

I took two batteries with me both fully charged, I used one battery all day Friday which consisted of 3 x 15min test/practice sessions and then a single 20minute qualifying session. So about 1hr and 5 mins of track time in total for the day.

Saturday morning I removed Fridays battery and put on a fresh battery and did a ten minute practice session and then 2 x 8 lap races which were about 17mins running in total each so maybe 45mins of total run time for the day.

At no point did I charge either battery during the weekend and the bike ran 100% all weekend. I forgot to put a multi meter on them when I got everything unloaded on Sunday and put the batteries on charge but I think the one that I used on Friday had the battery charger guage on about 5 amps when it was charging so was maybe getting towards being low.
