Hello, I need a new clutch cable spring. Where it attaches to the arm on the case. Its for an 87 trx but the motor is an 85 atc. Not sure if that makes a difference. Let me know if anyone can help or has a part number? Thanks

Same Clutch Arm Return Spring for all ATC250R 85-86 & TRX250R 86-89.

AS Matuus stated; in stock New #22815-HA2-670 (ONLY) at BDT. Plus along with the Spring, BDT stocks the OEM Washer New and also the complete Clutch Arm also New.

These can only be found at BDT Motorsports, and no they are not listed. If you want them; call or email BDT to order.

Totally not needed just makes your clutch harder to pull

I guess everyone is entitled to their own opinion, however; I will make the case why the Clutch Spring is a Needed item. A few points:

Honda Engineer’s are on point when designing components & their function for the 250R.
  • Yes, the clutch will function without the Spring in place.
  • No, it will NOT function correctly without the Spring in place.
  • The clutch return Spring does NOT add any real measurable tension to the clutch pull
  • The function of the Clutch Return Spring is to keep a constant force on the Clutch Rod & Arm Pocket.
  • Without the return Spring; the Clutch Rod will Float back and forth .5-.75MM based on stack up tolerances. During engine operation, a Clutch Arm without a return Spring will bounce/pound/vibrate against the Clutch Arm Internal Pocket creating a burr & excessive wear.
Run your Clutch Arm Lever return Spring; it was designed to insure correct Clutch Function with minimal Clutch Arm Pocket wear.

Funny how none of the Honda CR250s from 92 up had a clutch return spring on the case lever, mabey the Honda engineers were more concerned with a light pull at the lever and not excessive wear. In the 20 some years of riding and racing District 7 and Nationals without a return spring, I have never had any wear that I can see on the componentes, Oh by the way thanks for allowing me an opinion
 
In referencing models to compare to the Honda ATC250R 85-86 & TRX86-89, the CR250R after 92 is NOT an ‘Apples to Apples’ comparison, it is also outside the relevant 250R years of 85-89 for this discussion, based on this thread, and what the OP asked.

The CR250r’s also did not have a Counter Balancer, and only Two wheels, vs 3 & 4 for Trikes and Quads…. guess on these two features alone & based on your ‘flawed’ analogy; Honda engineers also did not know what they had designed or why…. Comical.

Just out of curiosity... How would a counter balancer or an additional drive wheel cause a measurable amount of wear over a single drive wheel or lack of a counter balancer?
Also, if honda engineers got it right and we shouldn't deviate from their design, how is it that there is any justification for aftermarket upgrades? I don't see 85-89 technology really keeping up with 2020's technology.
Additionally Matt seems to have 20 years of successful real world experience going without the clutch arm spring. If a nay sayer can show proof that you absolutely need the spring that would make it easier to believe.

Agreed Matuus. This is getting out of hand.

Rob79 this post needs to go no further. BDT has the parts your looking for. Run what you would like and buy from who you like my friend the choice is yours. 🍻🍻
Agreed! Already sent Carlos an email. Everytime I ask a question it turns to an argument. I don't get it

Out of curiosity, why do you think it is necessary to chime in here? Maybe Matt250r21 is the new scrappy bandwagon to jump on because he has posted something contradictory to Carlos?
Matt250r21 was doing just fine arguing his point, and the OP got a couple of different opinions on the Clutch spring. Unless you wanted to add your personal experience using or not using the spring I don’t see how your post contributed anything, but then again we all know what your primary objective is here on this forum.

I guess you just could not help yourself.
 
Carlos your business plan has always perplexed me, insult a shrinking customer base of a 30yr old quad. You will never see the owners of ESR LED Sparks or anyone else do that. I wonder why,

I know what worked for me racing A class for years and I can tell you 20 minutes around the roughest MX tracks in the country require every advantage, for me getting rid of the spring was just one of the mods
