Heelclicker and yamaha springs

[saskattakman]

im in the process of clutching my xtx and im running a green white green but cant get enough rpms out of it 8600 or so...will a heelcliclicker black or white give me more rpms. im looking for a bit lower start with a heavier finish

Not sure what weights you are running?

But Pink-green-pink has a little more finish and lower for engagement.

You dont adjust your shift rpms with the spring you do it with the weights . The spring controlls engagement . It sounds like you may have to pull some out of tip .

You need a primary spring with more spring rate. Spring rate controls the rpm shift out while the preload affects engagement. Pink Green Pink would be a good choice. Engagement can also be controlled by your clutch weights depending on what you have. I have Supreme Tool weights which allows me to put added weight in heel by pin to ease engagement and get the weight moving. Target rpm shift first which is your main concern. Engagement you can live with if not perfect there is always a sacrifice.

If you are OK with your eng RPM you need a spring with higer rate as bushman stated.The HC black with 14.5 rollers are around 35-3600 eng.Then you can finetune with the tip weight.

ive tried a 142 spring rate from the 136 and brought my rpms up slightly but not enough. im runnin a 45 helix with the 1.75 backcountry track. if i go back to my 39 helix all i do is hit rev limiter and lose top end speed. so im running 4.5 slug in the heel with a 1 gram washer and it still hits the limiter. running 15.5 mm roller as well

Try the stock 43*...... if you were hitting 8600 before and it went up slightly, that sounds pretty close to me

Last year when I did some testing my xtx ran stronger at 8500-8600......than it did at 8900-9000.
