    Checked the Moto Tassinari reeds today, installed new 250 hours ago, they were totally wear free on today inspection, my ride style is 99% idling around. MT recommends checking every XX# of hours. But considering the low rpm total count on my bike, I waited. 0615191352-01.jpg

    I splurged and bought a 2017 300 2T on Friday. Lesson learned: don't ride new bikes at meets. I rode the Beta I bought, a 2018 TRS, and 2018 Sherco 300 back-to-back-to-back. The TRS seemed overly responsive for me, someone who is only starting their second trials season. The Sherco felt kinda similar my 2001 Sherco 2.9, but tight and fresh; I wasn't WOWED by it like I was the other two (in my head?). I went with the Beta because it was a little more affordable and I liked it a bit more than the Sherco. This Beta is shorter than my old bike (as noticed when loading in my Tacoma) and loves to get on its back wheel. It's incredible how much more willing it is to wheelie and stay there. I've never managed to hold wheelie like this on my Sherco. My wheelies still aren't impressive or good, but this Beta feels right mid-wheelie.

    Somehow, the clutch on this Beta isn't nearly as bad as people online make it out to be. Not quite as progressive as my old Sherco, or the 2018 Sherco I rode for a little bit, but perfectly usable and predicable. Then again, I'm a complete noob and these are just uneducated opinions, formed after ~15 minutes on each bike.

    Anyway, expect some stupid questions from me in the near-near future. Starting with: what do people do about the CDI and ignition coil on these bikes? Especially the coil, it just sticks out there waiting to get smashed. Should I run a loose ziptie (or safety wire) from the coil to something else to prevent it from completely falling off when I crash? The CDI placement is also puzzling, but looks like it won't be the first thing to hit the ground. There's a CDI guard available, but I'm skeptical.

    Is it enough to replace the two rearmost back fender bolts with zipties or should I also trim (maybe remove?) that little lip that holds onto the airbox to the fender can pop off a little easier when I loop the bike?

    Do not cut the lip. Auto trim push tabs would work better. I still have not broke a rear fender yet. But the front fender could use some large washers.

    My old fender didn't have a lip. The air filter would get filled with rocks and sticks and stuff. You want the lip.

    Thanks guys. I'm glad I asked!

    Any tips about relocating/protecting the ignition coil, and to a lesser extent, the CDI?

    Leave it be. It's not as vulnerable as you think.

    Last one before I leave for a meet: should I trust my chain alignment tool (just got a motion pro yesterday, no experience with it otherwise) or the snails? Having my snails off by 2 or 3 positions is triggering. :twitch

    Anything I should be checking that might me upsetting the alignment?

    I know on my Daughters GG 125 I trust the chain alignment tool way more than my snail cams. They are off by at lest 3 positions to keep the wheel strait.

    I had the chance to ride an EVO 250 at a Beta demo event and am considering buying one. I was told by a dealer that the Beta's had issues with the coolant in the water pump reacting with the magnesium cover causing corrosion that can eventually allow coolant to get in to the engine and mix with the oil (hope I described that somewhat correctly!). I did a little searching on the internet, but all the instances I found were on the Rev3's. Did this issue carry over to the EVO's? Do the non-factory EVO's have magnesium covers? I also read about the impeller in the water pump sometimes melting or coming apart. Is that a common issue, and is that why I see Jitsie makes an aluminum water pump kit with aluminum impeller? Are there any other issues that I should know of before purchasing? I'm a slower female rider that would be using this as a lightweight trail bike and would be riding alone some of the time, so I need something that is going to reliable.

    EVO 250 is a great bike. Have had one for 4 years no problems with the impeller. Have heard of this problem with a very few Betas. Also have heard of the problem with other brands. Easy fix it it does become a problem. Go ahead and buy the bike you well be happy.

    Unless I am mistaken the impeller issue was only on the 4T bikes and very few in the grand scheme reported.

    You are reading the wrong info. The Beta two stroke is the most reliable trials bike available. And have been around longer than any current manufacturer.

    I found a 2009 evo 290 that’s appealing in a reasonable drive from me. Anything to look for with this year? Im pretty sure 09 was the year the evo was introduced.

    Holy crap is the air filter on my bike tiny! Anyone have experience with the Jitsie "race" air filter? I'm about to buy some junk from The Splat Shop and figured I would ask.

    Any other Beta parts I should consider buying? I have clutch/brake levers, brake pads, spare throttle wheel/cover, and grips.

    Check the fit on the Jitsie air filter, When I got one, I checked it after a short ride and it slipped off a bit on the long length area, I used popsicle sticks and shimmed it in there, and no more slip.

    What is the elevation overlap between the regular and light weight carb springs for the 4t? I moved to Montana and will be riding from 2,000 ft to 8,000 ft.
