10/30/2023 9:05am Since last time I used the bike passed few months. I drained out the fuel but unfortunately seems like was not enough. The oil solidify in the main jet and also in the secondary and it was quite difficult to cleaned out properly.

See my response on this thread: https://www.vitalmx.com/forums/tech-helprace-shop/ebay-radiators Good rads for the money but a little weak. I suggest welding some braces as I did on them before use. Since I've braced them they've been very solid.

10/12/2023 7:54am in the end I bought a set of GPI radiator. From first look seems solid, let’s see if they fit and cool the bike properli. At least all the fixing points are much stronger than std radiator that are broken already

10/6/2023 1:58am Question for the user. Someone has experience with GPI racing radiators? It worth to buy them or the quality is low? Are they enough well done to match plastics etc?

You're probably not going to find a plot like that because most companies selling a lowering link don't do any sort of analysis or measurement, they just make a longer link. If their objective is to simply lower the rear end, that will do it. The only ones that might have a plot like that are ones that (correctly) re-designed the knuckle as well as the link since they'd need to know the motion ratio curve to make any sort of improvement. There are only a handful of companies who do that and few that would share the curves. Regardless...

9/1/2023 12:55am Hello everyone, I saw online many kit for lowering the yz450f and seems like the link has been the same for a long time now (form 2018 at least). I would like to understand how the link ratio changed with this lowering kit. From my experience elongating the pull rod the link ratio is going to move to a more...

That bike looks incredibly good to me. I really wanted to do the pink/magenta set up of the YZ vs the teal for my WR. With those black rims just simply stunning to me. Damn me and my need to look stock and original. I have to restore these older bikes with the broadest appeal. Great job and I love the look. Your photo composition was excellent. You must have some background in photography as most wouldn’t have composed their shot like that.

8/26/2023 12:42am Restoring a bike is stressful 😂 I mounted the oem silencer and realized that the exhaust is not the 1991 but probably the 1990 or older so the two parts doesn’t match. Now I have doubt if modify this exhaust (need to cut a little the final part) or try to find its own ( difficult to find in good...

8/13/2023 12:59pm Forks works great, but it is slightly longer than standard and much harder as setting so the bike is a little rotated backwards. I think that the chassis has already more angled fork head respect modern bikes and agility and rider position is not the best with this setup. I tried to have more front height and reduce a little...

This is what I wrote on one of my restores. This is how I Cerakote. How I use Cerakote. Cerakote main Site-Press Me Cerakote is a fantastic product to use. It comes in the color so desired along with a small bottle of hardener in the oven cure series. The oven cure or heat cure tend to have the most amount of desirable attributes vs an air dry. The air dry product line do not use a separate hardener. You just pour the contents in and spray. Although Duracoat was cheaper as I remember, it also featured a catalyzing agent...
