future gasgas owner

[BUBBAHUSKY]

I ride 07 Husky wr250. Spoke with Clay and think I'm sold. Mostly ride tight woods and undecided between 250 or 300. All my friends ride orange not me. I'm 49 but still love to ride hope gasgas can be the next.

Go w the 300. You wont be disappointed.

I'm a small guy, about 5'7", 155lb's buck naked and I prefer the 250. The 300 just has a heavier feel to it even though it is the exact same bike.

This topics been covered a few times recently so a search should turn up some good results with more opinons. Basically both bikes will do the same as eachother. The 250 just revs a bit more and pulls your arms a bit less.

Below is some sims of both my 250 set up options (S3 Race ported cylinder and 1.25mm squish - Red line), and my 300 (Ports timed for top end, High comp S3 insert, 1.9mm squish).

250/300 its a difficult choice for sure. I like the 250 in faster single track and more open areas. And the 300 for tight rocky technical riding. I have a strange passion for riding in big rocks. So I tend to ride the 300 more.

I've seen several different times on here were you guys show graphs of the power characteristics of the two bikes. Are these graphs from a dyno or do you guys have a different method of figuring this out? It would sure be nice to have a dyno for tuning but too costly for me.

Rosco,

All the graphs I have posted were provided by Dave (dmcca). He is getting some really positive feedback here in Australia for his 2T engine tuning skills, workmanship, and work ethics.

Basically the graphs are simulated dyno runs. As with any software, the data output is only ever as good as the data input, and doesn't neccessarily cross over 100% to real dyno figures where there are more variables at work. I'm not sure which software package Dave uses, but he has had his hands on several Gassers now (among other bikes). What the sims allow for is to see how changing the port sizes, timing, powervalve timing, squish band, compression ratio, etc all effect the powercurve prior to physically implementing them.
